Are you using Java?
Yes, I am using Java 12. I tried to extract the critical code into two simple methods to show what I called in essence. Was not really a reproducer. Your code works for me as well. Actually, it is hard to trace the reason for this error because all I get is the stacktrace which shows errors coming from Strata.
I imagine there is a race condition somewhere
I will try to find the reason and let you know..I need some time..

Have you got some sample code that fails. I can't find anything immediately wrong. thanks

For example, the following code (version 1) works and no error is thrown:
// this works (version 1):
Set<Boolean> check{
// using stream()-version
return ids.stream().flatMap(id -> check(id).stream()).collect(Collectors.toSet());
}
boolean check(HolidayCalendarId id){
return id.resolve(ReferenceData.standard()).isHoliday(LocalDate.now());
}
The following code (version 2) does NOT work and throws the exception:
// this fails because of parallelStream()
Set<Boolean> check{
// using parallelStream()-version
return ids.parallelStream().flatMap(id -> check(id).stream()).collect(Collectors.toSet());
}
boolean check(HolidayCalendarId id){
return id.resolve(ReferenceData.standard()).isHoliday(LocalDate.now());
}
The stacktrace when using parallelStream()-version:

Running this Java code on Java 8 or 11 with 38,000 IDs results in no error:
public static void main(String[] args) {
check2();
System.out.println("done");
}
static Set<Boolean> check2() {
return IDS.parallelStream().flatMap(id -> Stream.of(check(id))).collect(Collectors.toSet());
}
static boolean check(HolidayCalendarId id) {
return id.resolve(ReferenceData.standard()).isHoliday(LocalDate.now());
}
Are you using Java? (Your original code did not compile).
I imagine there is a race condition somewhere, but it is hard to examine without a reproducer
